Thank you very much for your reply.
Finally we have successfully configure the xmpp gateway to work (both
presence and IM) with another kamailio server which provide SIP
REGISTRAR/PROXY/PRESENCE (with integrated xcap function).
The key points are to put the server address parameter of presence and
pua_xmpp module to the gateway itself instead of the main Presence
Server of the SIP/SIMPLE domains. But the outbound_proxy of the xmpp
module must point to the main PROXY server of the SIP/SIMPLE domains.
The outbound_proxy of pua is not specify, so it point itself.
following are this part of the configuration:
modparam("xmpp", "outbound_proxy", "<main_proxy_uri>")
modparam("presence", "server_address", "sip:10.10.5.210:5060")
modparam("pua_xmpp", "server_address", "sip:10.10.5.210:5060")
Now it works fine withe some bugs:
- xmpp add sip contact: ok
- sip add xmpp contact: ok
- xmpp see the sip contact presence: ok
- sip see the xmpp contact presence: ok
- sip IM to xmpp: ok
- xmpp IM to sip: ok
the bugs we found are following:
- the online/offline status is ok in both direction (SIP <--> XMPP)
- other status (away/busy) is not ok from XMPP to SIP
- busy status is not ok from SIP to XMPP
- each time XMPP contact change the status, triger a new SUBSCRIBE in xmpp
gateway which generate multiple same subscriptions with different callid
in both active_watchers and pua tables. This also makes multiple
multiple NOTIFY
generation from the main Presence Server to GW when the SIP contact change
it's status
We have make the following patches in the pua_xmpp module that fix the
above bugs. Hope it can help.
